A suspension system (1) for a motor vehicle having a telescopic spring cylinder (2), having two spring stages (A, B), namely one main cylinder (8) as a first spring stage (A) and an auxiliary cylinder (10) as a second spring stage (B). An auxiliary piston (26) with an auxiliary piston rod (28) is displaced in the auxiliary cylinder (10). Inside the auxiliary cylinder (10), the auxiliary piston (26) is acted upon by a spring pressure (p2) for decompression, which is generated by a pneumatic pressure medium (PM) inside the auxiliary cylinder (10). The auxiliary piston (26) is indirectly acted upon by the spring pressure (p2) via an hydraulic medium (HM) inside the auxiliary cylinder (10). Peripheral seals (30, 38) arranged between the auxiliary cylinder (10) and the auxiliary piston (26), and the auxiliary piston rod (28) are separated from the pneumatic pressure medium (PM) via the hydraulic medium (HM).
